Wiring Diagrams
RS-485 control
Shows three devices (Device - 1, Device - 2, Device - 3) connected in a chain. Each device receives power from a 'POWER BOX' (Line 1, 2, or 3) and is connected to an 'LED Screen' (Line 1, 2, or 3). The devices are interconnected via RS-485 communication ports. A separate RS-485 Controller is shown connected to Device - 1. The diagram indicates that the termination switch should be set to 'on'.
I/O port control
Shows three devices connected similarly to the RS-485 control diagram, but instead of RS-485, they are controlled via a 'Switch' connected to Device - 1, which then controls the other devices. Each device receives power from a 'POWER BOX' (Line 1, 2, or 3) and is connected to an 'LED Screen' (Line 1, 2, or 3).
RS-485 control + I/O port control
Combines both RS-485 communication and I/O port control. Devices are connected to a 'POWER BOX' and 'LED Screen'. An RS-485 Controller is connected to Device - 1, and a 'Switch' is also connected to Device - 1. The diagram indicates that the termination switch should be set to 'on'.
Note
(1), (2), (3) Power Supply, RS-485 Controller and Switch are not included in the scope of delivery and has to be purchased externally from a third-party provider.
(2) The RS-485 Controller can be any device, which communicates via RS-485 protocol (e.g. PC, Mediacontroller, KNX or EIB device).
(3) Switch can be for example a potential free output of an KNX or EIB device.
Mounting On Din Rail
Using 35mm DIN rail.
Mounting
Diagram A shows the mounting process: Place the upper keyway hooks onto the top edge of DIN rail, then push toward the mounting surface and check that it is attached securely.
Removal
Diagram B shows the removal process: Use a suitable screwdriver to release the locking mechanism of the device, then carefully lift it off the DIN rail.
Address Setting
Method for two devices
Illustrates Device - 1 as Master (Address=02) and Device - 2 as Slave (Address=XX -> 03). Both are connected to a DC Power Supply (+12V). The procedure involves connecting, switching on power, and pressing the MODE button on the master device for at least 15 seconds within 10 seconds of power-on. The slave address is set to master address + 1 and confirmed by the STATUS LED flashing 6 times.
Method for more devices
Shows a two-step process. STEP 1: Device - 1 (Master, Address=02) and Device - 2 (Slave, Address=XX -> 03) are connected and configured as in the two-device method. STEP 2: Device - 2 then becomes the Master (Address=03) and Device - 3 becomes the Slave (Address=XX -> 04), with similar connection and configuration steps. Both steps require DC Power Supply (+12V).
Note: Power Supply is not included in the scope of delivery and has to be purchased externally from a third-party provider. The slave device address will be set to master address + 1. The slave device will confirm the new address with 6-times fast flashing of the "STATUS" LED.

Explanations About Operations
(1) AC OUT control and operation after turning the devices on
The first scenario shows AC OUT turning on 30 seconds after devices are powered on, if controlled via Control In or RS-485 within 30 seconds of power-on. The ON/OFF LED flashes. The second scenario shows AC OUT turning on immediately if controlled via Control In or RS-485 after 30 seconds have passed since device power-on.
(2) AC OUT control and operation
Shows AC OUT turning on 30 seconds after a previous AC OUT 'on' state, if the initial 'on' command was given within 30 seconds of the device being set to 'on'. The ON/OFF LED flashes.
(3) Timing of Control out output
Control Out turns on 1.8 seconds after AC OUT is set to on using Control In or RS-485. Control Out turns immediately off when AC OUT is set to off using Control In or RS-485.
(4) Operation when an error occurs
High-temperature protection operation: AC OUT turns off when the internal temperature reaches 60°C or higher and turns on again when the internal temperature decreases to 55°C or lower.
High-voltage protection operation: AC OUT turns off when the voltage reaches 14 V or higher and turns on again when the voltage decreases to 13.5 V or lower.
Low-voltage protection operation: AC OUT turns off when the voltage decreases to 10 V or lower and turns on again when the voltage increases to 10.5 V or higher.
The diagrams illustrate command sequences (reqps, reqst, reqt1s, requss) and LED indicator status (ON/OFF, STATUS) during these operations.
